Inventor: WALLENFELS KURT PROF DR
IPC: C07C255/51
Filed: 1972-02-04
Abstract: Cpds. of formula (I) (where R is Cl or CN) are prepd. by reacting 1,3,5-trichloro-2,4,6-tricyano-benzene successively with (a) an alkali alcoholate (b) a heteropolar cyanide (pref. NaCN) and (c) a chlorinating agent in the presence of an org. base. (I; R = Cl) can be obtd. in almost quantitative yield when reaction time in step (b) is relatively short (ca. 90-120 mins.) and (I; R = CN) can be obtd. in considerable yields when reaction time in step (b) is several (pref. 3-6) hrs. (I; R = CN) forms crystalline complexes with aromatic hydrocarbons and can be used for their qualitative detection or for pptg. them from solns; it also has interesting semiconductor props. Both cpds. (I) are useful as inters. e.g. for potential insecticides and fungicides, polymer components and coupling prods.

Title: Flanged seam arc welding eg for radiators - by oscillating heads and direct with superimposed pulsed current
Inventor: HILDEBRANDT PETER DR ING
IPC: B23K9/09
Filed: 1973-03-19
Abstract: An arc welding system of sheet metal articles with a flanged joint (space heating radiators) where the electrode cannot be centred exactly over the seam uses an oscillating welding head with an amplitude across the seam of plus-or-minus 1.5-2 mm. The welding current is a bsic constant current supplied from a source with a drooping characteristic. Current pulses superimposed on this are supplied by a source with a constant voltage characteristic. Method allows faster welding rates, combined with a better penetration of the seam. The welding arc is not extinguished and defective welds are eliminated.

Title: Molten metal bath coating material - dried to granules after mixing fly ash with water glass in edge mill
Inventor: EITEL WILHELM DR RER NAT
IPC: B22D27/06
Filed: 1973-07-04
Abstract: A granulated cpd to cover molten steel baths is prepd by mixing the moistened refractory powder (fly ash) with a bonding agent (water glass) and turning it by an edge mill into a damp paste.

Title: Method for determining spatial position of a point - uses three optical angle measuring devices placed at the corners of a triangle
Inventor: PETER KLAUS-JUERGEN
IPC: G01S5/16
Filed: 1974-01-17
Abstract: The triangle is placed on a horizontal reference plane defined by two coordinate axes, and the angle measuring devices scan the monitored space. The point whose position is to be determined is defined by the point of intersection of three planes defined by the apparent angle of incidence of the point image on the above devices image planes. Coordinates of the point are calculated from the elevation angles of the three planes defined by the above point, and from the distances of the optical devices from the origin of a three-dimensional coordinate system, in accordance with specified expressions. These involve trigonometric equations for the coordinates x(P), y(P), z(P), of the point P in terms of its elevation angles, (alpha, beta, gamma). Computation is performed by a computer including a microprogram.

Title: Variable length vehicle windscreen wiper - has control cam pulling arm in to reach into corners of windscreen
Inventor: BERNAU KLAUS-JUERGEN
IPC: B60S1/36
Filed: 1975-04-15
Abstract: The windscreen wiper arm has a hollow base section (13) in which the drive shaft (7) is secured on a sliding mounting (21) with the mounting held in t he mid position by an internal spring (20). The hollow section thus extends beyond the pivot point of the wiper. The bottom end of the wiper arm is fitted with a sliding surface (16) which is guided by a profiled cam (3) as the wiper swings across the windscreen. The cam pulls the wiper arm inwards at the top of the sweep and at each end, while it allows the wiper arm to extend into the corners. This greatly improves the visibility for the driver without any complex wiper linkage.

Title: Low power limited gain amplifier - has balanced two transistor circuit with input and output transformers
Inventor: MATTY THOMAS C
IPC: B60L3/08
Filed: 1975-04-29
Abstract: The two transistor amplifier is for high reliability where a fixed gain is required. Input signals arrive via a centretapped transformer, each end of which feeds the base of an n.p.n. transistor operating in a class 'A' bias condition. A further centre - tapped transformer fed from the transistor emitters couples the amplifier into a filter and output circuit. In each base to transformer line is a resistor having a value very much higher than the impedance of the output transformer. The base or bias level is set by a two resistor potentiometer, the junction point of which feeds the input transformer centre - tap. Similarily the emitter circuit is grounded through the output transformer centre - tap and a C.R. potentiometer.

Title: Intruder resistant automatic roller shutter locking mechanism - with media in guideways and in last slat operating together, and interconnected
Inventor: BUTZBACH ARNOLD
IPC: E06B9/80
Filed: 1975-05-22
Abstract: The locking mechanism prevents a lowered roller shutter being raised by an unauthorised person. Locking bars (3, 4) are fitted in both shutter's guideways (1, 2) so as to operate in conjunction with stop or locking mechanisms (5, 6) closing slat (7), or the other slat. These bars automatically lock the lowered shutter under the influence of springs (8). The sets of bars for the two guideways are coupled to each other esp. for the unlocking process. They may be driven by electromagnets, and there may be a mechanical coupling in the fixed parts of the window or door frame. This is easily operated, with no need to open the window in order to lock or release it.
